MNL 330

MNL 330 nitrogen laser

The MNL 330 is the ideal light source for bio-reader systems and MALDI-TOF imaging. Compact, reliable and cost-efficient, it can provide pulse energies up to 48 µJ and repetition rates up to 300 Hz

  • Wavelength 337,1 nm
  • Long operating life
  • Cost-effective solution
  • Application in Bioreaders
  • Alternative to flash lamps


The Mini Nitrogen Laser MNL 330 is characterized by its long lifetime, low energy decay and high precision. This is achieved by the patented innovations:

  • Sealed cartridge in metal-ceramics technology

The MNL 330 presents the advantages of modern laser technology. Only an external trigger signal is required for its operation. That is the reason why its use is so simple. The standard version with free beam can be equipped with an optical fiber for the light output allowing the best integration into the customers‘ applications.

Compared to flash lamps, the MNL 330 provides several benefits: it couples clearly more light in an optical fibre or even in several simultaneously, delivers pulses with higher energy, lower pulse duration (3 ns, no afterglow) and considerably lower spectral bandwidth (excitation wavelength  and detection wavelength can be very close). Moreover it is possible to couple the MNL 330 with a tuning module in order to provide several wavelengths of the whole visible spectrum

The air-cooled MNL 330 is supplied with a low voltage of 24 V DC / 60W. A wide range power supply (100 – 240 V, 50 – 60 Hz) can be obtained from LTB, if required. Small, compact, with a total volume of 2.2 litres, the MNL 330 will provide you the best performance as UV-light source for your reader.
